A. Methods of Communication:
(1) Radiation disturbance
(2) Conduction disturbance
B. Immunity Methods
With regard to nuisance signals transmitted by radiation methods, they are primarily weakened by wiring and shielding the radioactive source and the disturbed lines.
As for the nuisance signal transmitted through the line, it is mainly handled by installing filters, reactors or magnetic rings on the input and output sides of the inverter.
The specific methods and precautions are as follows:
(1) The signal line and the power line should be vertically crossed or slotted and routed.
(2) Do not choose wires of different metals to connect with each other.
(3) The shielding pipe (layer) should be reliably grounded, and ensure continuous and reliable grounding on all lengths.
(4) Twisted pair shielded cables should be used in signal circuits.
(5) The shield connection address should be as far away from the inverter as possible and separated from the inverter connection address.
(6) The magnetic ring can be used on the input power line and output line of the inverter, and the specific method is: the input line is wound 4 times in the same direction, and the output line is wound 3 times in the same direction. When winding, it is necessary to pay attention to the magnetic ring as close to the inverter as possible.
(7) Generally, shielding and other anti-annoying methods can be adopted for the disturbed equipment and instruments.

Precautions for external wiring of the inverter
In the process of connecting the line of the inverter, it is necessary to pay attention to the following aspects:
1. The power supply must be connected to the main circuit power terminal L1/R, L2/S, L3/T, if the power supply is connected to other terminals by mistake, the inverter will be damaged.
2. It is necessary for the grounding terminal to be well connected.

The reason for the frequent tripping of Schneider leakage switches
1. Defective device
The lead wire of each pile head is not firmly connected and loosened for a long time, which will cause the pile to heat and oxidize, burn out the outer insulation of the wire, and announce sparks and burnt smell, forming undervoltage of the line, and the air switch action.
2. The leakage switch does not match the load
The actual electricity load of the home is large ...
